Patented June '6. 1922.

Application filed October 22. 1319. Serial No. 332,438.

in the'c'it and county of Philadelphia,

State of ennsylv'ania, have invented new and useful Improvements in Interrupter Mechanism, of which the following is a specification.

.My invention relates to structure for interrupting an"elec tric'circuit, and particularly for; interrupting theprimary of the ignition circuit of anzinternal combustion ,My. inventi0n resides in apparatus of the character referred to comprising a base or plate member of insulating material in which isembedded a condenser and suitable inserts serving as terminals and supports for. the interrupter members, suitable connections being formed or embedded within the'jins'ulating base.

My invention resides in apparatus of the character hereinafter described and claimed.

. For an. illustration of some of the many forms In invention may take, reference is to be ha to the accompanying drawing, in which:

Fig. 1 is a plan view of the base plate. Fig. 2.,is a side elevational view of the same.

Fig. 3 is a fragmentary sectional view taken on the line 33 of Fig. 1.

Fig. 4 is a fragmentary sectional view takez'ron the line 4- 4, Fig. 1.

Fig. 5 is a fragmentary sectional view taken on the line 5-.-5, Fig. 1.

Fig. .6 is a vertical sectional view, partly in, elevation, of assembledfinterrupter and distributor -meohanism. embodying my invention V t Fig. 7 isa plan view of the structure illustrated in Fig. 6, with the cap and distributor arm removed; I

Fig. 8 is a. side elevational view of a modified structure embodying my invention.

Referring to the drawings, the base plate, supporting member or base plate 1 is of insulating. material, preferably of condensite, bakelite or other suitable mold-a ble insulating material.

Completely enclosed within the member 1 is the condenser C, of any suitable type, for example, rolled tin foil and paper,

placed 1n the mold for themember l and molded within the same as the member 1 is g made, the condenser beingthus compressed by insulating material which serves alsome-i protect chanically. to protect it and to from moisture.

exteriorly knurled or roughene and interiorly threaded, and-preferably having.

upstanding Molded within the base plate l is the post 7 rising abovethe uppenface of,the'

member 1 and enclosed in the integral lug 8.

In its upper end the post 7 interiorly,

screw threaded to receive the screw 9 which holds the metallic member 10 firmly a ainstthe fiat upper surface of the lug 8. p011 the downwardly extending end 11 of the member 10 is secured the stationary interrupter contact 12, with which co-actsthe movable interrupter contact 13 carried by the arm 14 having at its free end the cam engaging tip or shoe 15 and secured at its other end to the leaf spring 16, secured to the verticall extending arm ."17 of the bracket member whose horizontal member 18 is secured by screw 19 threaded into the post or bushing 20 molded in the base 1 and flush at its upper end with the horizontal surface of the slightly raised molded portion 21, having molded therein :two depressions 22, .22, in which engage the projections. 23, 23' on the under side of the plate 18.

A conductor 24, molded within the base member 1, connects the terminal bushing 3 with the post 7. and with one terminal 25 of the condenser C. A conductor 26, molded within the base 1, connects the other terminal 27 of the condenser C with the post 20 and the latter with the terminal bushing 2.

Extending centrally through the base member 1 is the hole 28, upwardly through which extends, Figs. 6 and 7, the cam shaft 29.

The base plate 1 has integral therewith the lugs 30 having the counterbored holes 31 through which extend screws 32 engag- ,..60 There are molded in the member l 'thb, metal terminal bushings 2 and-3,; refer-ably ing metallic housing 33, enclosing gOVQLIlOl strncture,,G charging, as well understood injhje' art,,with,changes in speed the angular relation between the aforesaid cam shaft 29 and the engine driven timer shaft 31, which is journalled within the hub 35, which may be integral with the member 33.

Enclosing the interrupter mechanism is.

the cap- 38; also preferably. ofmolded. insul'ati-n material; resting atits. lower edge Ee riin-39 of the member. 1, andlield b '=a suitqbleiclampi means, not s iown. Vaitliiirthecap are dis p osed'the usual high tension distributor terminals 40, 4-0, one i or eaeEkcyl-i iider of tllQdHOtOl', and ,the central h-igli ten'sion 'terminal tl, connected to one terminal ofthe secondary of the ignition iiidiiction coil; and in, electrical communication withthe-contact 42 carried by and retating; with the distributor arm 43, preferablj o-fimoldedinsulating material, liar ingasocket within which is the tongue 4i en agin iir-theslotafi, Fig. 7, in the upper en of t "e cam shaft 29; At the outer end of'th'e-distributor arm 43 is the usual contact'Afi iii-electricaljcommunication through tl1Q-COIltflClT-12Witli th'e higl tension contact 41'.

W her the apparatus is in operation. in a manner well understood in the art. with the interrupter mechanism, described connected in-series in the'primary circuit of the induct-ion coil by connecting the terminals 4 and 5' with conductors (not shown) extending throughan aperture (not shown) in thc cap"38;, the interrupter contact 13 engages with and'separates from the stationary contact12, therebv interrupting the primary circuit;and-producing high tension impulses in the secondary circuit. which impulses are distributedfby the aforementioned distributor mechanism to the spark plugs of the respectiyetcylinders of'the, motor. The condenser C, as usual; redncesthe sparking at'tlie interrupter contacts 19 and 13, and so increases, the intensity of the secondary impulses, the condenser being connected. as well understood in the art, across the break between the interrupter contacts 12 and 13.
